Do you have the same behaviour if you connect another external hdd ?<br />

</div>


<div>
USB 3.0 allows more current than USB 2.0 which this motherboard has. <br />
USB 2.0 provides power up to 500 mA whereas USB 3.0 caters up to 900 mA, resulting in an increase in total power delivery from 2.5 W to 4.5 W <br />
If the drive is powered by the USB cable either plug it into a powered hub or even better get a pcie USB3.0 card that has a SATA power input and use this card (it will speed things up considerably)
</div>


<div>
It could be the usb 3.0 drive is drawing more power than what the system can handle causing the event ID 41.
</div>


<div>
Thank you both. &nbsp;Prior to installing this 3TB external drive into the USB3 card, did minimal backups to other external USB2 drives without issues. &nbsp;When the new drive was installed, installed it onto an extended USB3 cable into the USB3 card and it started the backup. &nbsp;Wasn't there to monitor, but when I returned to the system, it was chaos. &nbsp;Was running the old Windows 7 BACKUP application to do a full system backup and had a tough time recovering this system. &nbsp;Was able to access the new USB drive to note that File History was there and completed. &nbsp;I was not there for another day or two, but here are some of the problems cited in the event viewer: &nbsp;Most often, Kernel Event 41 - CRITICAL, Lost power unexpectedly. &nbsp;Also in the event view under Device Manager these items noted:<br />
VIA HD Audio<br />
VIA HD Audio1<br />
MS Device Association Root Enumerator<br />
<br />
Other Event Log items were<br />
Event 507-ESSENT Faulty Hardware<br />
Unexpected Service Trap<br />
<br />
The STOP CODES that preceded many of these were fixed.<br />
<br />
Left that system to do full Viruscan and hope to return to it and provide more feedback asap.<br />
<br />
Thanks again.<br />
<br />
<br />
In Device Manager, uninstalled the LPT1 port I disabled in the BIOS and uninstalled many potential culprits.
</div>


<div>
Robert R: &nbsp;The power issue was my initial concern, but that's why I gave the specs of the Motherboard, assuming that would help clarify what power drain it can handle, or if it's a setting within the BIOS to change.
</div>


<div>
3TB external drive <b>into the USB3 card</b><br />
<br />
What USB3 card? the information you provided did not mention ANY USB3 card, the motherboard only has USB2 ports
</div>


<div>
I'm not there, working from memory and old scribbled notes so will need to get back on specifics on the installed card(s). &nbsp;There are two different Windows Pro desktop systems, two different places both of which have ASUS Motherboards and similar power problems.
</div>


<div>
They plugged an USB3 extension cord into a USB2 slot. &nbsp;my mistake. &nbsp;Much to learn about USB 3 HUBS that will improve these power problems on this ASUS MB as well as another with similar power problems on their P5LD2. Welcoming Hub recommendation.
</div>


<div>
some basics : <br />
usb 3 is backward compatible with USB 2<br />
usb 2 speed = 480 MBits usb 3 speed = up to 5 Gb &nbsp;= 625MByte/s =approx 10x usb 2 speed<br />
as for power usb 2 delivers over the connector a 5 V line at MAX 0.5 A = 2.5 W ( which often is not enough for external drives<br />
USb 3 delivers also 5 V but up to 2 A which normally is ample power for external drives<br />
<br />
post the dmp file if one is present for more info
</div>


<div>
I hope to see them later today or early tomorrow. &nbsp;When they did multiple reboots, and appeared improved they ran another full Viruscan and tried to change Windows settings after which the system abruptly rebooted with this message<br />
Unexpected Kernel Mode Trap<br />
Also stated problems with HELLO<br />
<br />
Thank you.
</div>


<div>
&gt;&gt; &nbsp;Unexpected Kernel Mode Trap &nbsp;&lt;&lt; &nbsp;that looks like a minidmp msg, so look for the dmp file
</div>


<div>
The only *.dmp file I find is 2014<br />
Cleaned the internals, changed HDMI cable, ran sfc /scannow<br />
No problems found there, but more to explore in the event log later today
</div>


<div>
is the system still set to make dmp files?
</div>


<div>
Not sure, nobus. &nbsp; Settings are a mess. &nbsp;How can I confirm? &nbsp;Too many folks have modified everything imaginable on this system.
</div>


<div>
look here : &nbsp; <a href="https://www.tenforums.com/tutorials/5560-configure-windows-10-create-minidump-bsod.html" rel="ugc">https://www.tenforums.com/tutorials/5560-configure-windows-10-create-minidump-bsod.html</a>&nbsp; .
</div>


<div>
When taking above actions, advised system managed paging file inadequate to support, changed from 200 mg to 500 mb min and 800 mb max to see if that helps and system stuck on reboot with more 41 events. &nbsp;Power suppoly is 600W<br />
<br />
Created MEMORY.dmp file, but don't have permissions to open or share, or stop shsaring this file. &nbsp;It's in the Windows directory and I have ADMIN access. &nbsp;<br />
gads WT...?
</div>


<div>
did you set it to make<b> MINI</b>dumps ?
</div>


<div>
I only created the Memory Dump vs. the minidumps. &nbsp;Will try again. &nbsp;Last effort resulted in reboot and BSOD. &nbsp;Thank you for hanging in there with me. &nbsp;I sure appreciate it. &nbsp;Working on another system this morning with similar problems you helped with before which was an upgrade from W/7 to Vista to Win10 Pro.
</div>

<div>
Did that except had the time to display item was checked. &nbsp;Again immediately rebooted to bsod. &nbsp;Tried logging in with second Administrator icon which deleted, changed password and booted to changed desktop followed by BSOD. The primary login icon no longer there, the only result found in the Windows directory on *.dmp query found only MEMORY.DMP file. At reboot memory check always ok. Wants BIOS Reset to default. long night.
</div>


<div>
&gt;&gt; &nbsp; Again immediately rebooted to bsod. &nbsp; &lt;&lt;&nbsp; i assume the change was not saved then, so try again<br />
anyway - how is your ext drive connected exactly now ?<br />
you can Always run sfc or a repair:<br />

All external drives disconnected. Should BIOS be reset to default settings, where parallel port not used disabled and pnp Os is enabled?
</div>


<div>
sfc and DISM processes prior to last BSOD sequences were ok<br />
But reset BIOS back to default, rebooted as Administrator in changed desktop, missing most apps. &nbsp;Cmd as Administrator found corruption, repaired. &nbsp;checked for CBS.log but log not found. changed Advanced settings to exactly your above image. More if or when minidmp found.
</div>


<div>
CBS log found in Windows Logs folder, but huge. &nbsp;Today's items there are bootstrap.dat , windowsupdate txt file and PFRO text file.<br />
The minidump from yesterday was found.<br />

Should I get another Motherboard? &nbsp;If so, which? &nbsp;Another system you helped with has had similar ongoing problems with remaining unresolved issues. &nbsp;Was also upgraded from Vista to Windows 10 Pro and is the ASUS P5LD2. &nbsp;For both motherboards, checked ASUS site and the most current, updated BIOS exists for both. &nbsp;Yet as I'm on that other system this morning, same issues as above.
</div>


<div>
well FYI i am running windows 10 on a P5G41-m and it runs fine, when it has 4 GB ram<br />
the only way to test it, is put win10 on that -or another disk from fresh, and check if it has problems ( they may stem from the 3 upgrades - or more : XP, Vista; W7 and W10<br />
you can get a hdd of 500 Gb for 20 $, or an 256 GB SSD for 30-40$
</div>


<div>
Thanks 🙏 <br />
Giving up on &nbsp;fixing and saving the old Apps <br />
Will try clean install
</div>


<div>
Asta, i often do a fresh install; i know it takes time to reinstall everything - but then you're sure it should work

ASUS Motherboard of Windows 10 Pro USB3 cause

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.
